For LWJGL 3 you may do this

import org.lwjgl.glfw.GLFW;
import org.lwjgl.glfw.GLFWScrollCallback;

// ...

float mouseWheelVelocity = 0;

GLFW.glfwSetScrollCallback(windowId, new GLFWScrollCallback() {
    @Override public void invoke (long win, double dx, double dy) {
        System.out.println(dy);
        mouseWheelVelocity = (float) dy;
    }
});

Replace windowId variable with yours. Make sure it's initialized by that time. Then you can save dy argument which shows change of the mouse wheel rotation (+1 and -1).

As specified on the lwjgl javadoc, try calling

    Mouse.getDWheel(); // Scroll amount
    Mouse.isButtonDown(2); // Scroll wheel pressed?
